Dancer IRCD: CODE http://freenode.net/dancer_ircd.shtml This runs the Freenode Network ircd-ratbox: CODE http://www.ircd-ratbox.org/index2.shtml This runs the EFNet. Both are damn stable and robust - can guess from the networks they run Hope this is helpful to people who want to start their own IRC networks. Also checkout Unreal IRCD, this has to be my all time favourite, very easy to install and very easy to intergrate services. CODE http://www.unrealircd.com
